SA ETY ALERTS
The symbols below are used on the equipment and throughout this
document to draw the user’s attention to important operational and
safety information.
CAUTION:
Read the manual thoroughly
before installing and operating
the equipment.
CAUTION OR DANGER:
Electrical shock hazard
All safety related instructions that appear in the manual must be
observed to ensure personal safety and to prevent damage to either
the instrument or the system. f the instrument is used in a manner not
specified by the manufacturer, the protection provided by the
equipment may be impaired.
INSTALLATION / CONECTIONS
The controller must be fastened on a panel, following the sequence
of steps described below:
•Prepare a panel cut-out of 46 x 46 mm;
•Remove the mounting clamps from the controller;
•nsert the controller into the panel cut-out;
•Slide the mounting clamp from the rear to a firm grip at the panel.
ELECTRICAL CONNECTIONS
ig. 01 below shows the electrical terminals of the controller:
ig. 01 - Connections of the back panel
RECOMMENDATIONS OR THE INSTALLATION
•All electrical connections are made to the screw terminals at the
rear of the controller.
•To minimize the pick-up of electrical noise, the low voltage DC
connections and the sensor input wiring should be routed away
from high-current power conductors. f this is impractical, use
shielded cables. n general, keep cable lengths to a minimum.
•All electronic instruments must be powered by a clean mains
supply, proper for instrumentation.
•t is strongly recommended to apply RC'S F LTERS (noise
suppressor) to contactor coils, solenoids, etc. n any application it
is essential to consider what can happen when any part of the
system fails. The controller features by themselves can not assure
total protection.

Table 02 – Alarm functions
INITIAL BLOCKING O ALARM
The option to Block initial alarms inhibits the alarms in the case that
there is an alarm condition present on startup. The alarm will be
enabled only after the occurrence of a non alarm condition.
nitial Blocking is useful, for example, in the initialization of process
control operations when the value of the PV is still far from the SP
value. Hence the system waits for alarm situations and unwanted
alarms are avoided.
The initial blocking is disabled for the sensor break alarm function
ierr
ierrierr
ierr.
O SET
Allows fine adjustments to the PV reading for compensation of
sensor error. Offset allows measurements errors to be corrected
when the occur, for example after the substitution of a temperature
sensor.
UNCTION LBD – LOOP BREAK DETECTION
The parameter defines a time interval, in minutes, within which the
PV is expect to react to a control output signal. f the PV does not
react properly within the time interval configured in lbd.t
lbd.tlbd.t
lbd.t, the
controller interprets this as a control loop break and signals this
occurrence in the display.
f the lbd.t
lbd.tlbd.t
lbd.t parameter is set to 0 (zero) then this function is disabled.
This function allows the user to detect problems in the installation, for
example an actuator with a defect, a failure of supply power, etc.
A LBD event may be sent to any output channel. Simply configure
the LDB function to the desired output channel (OUT1 or OUT2): the
selected output will be activated when a LDB condition is detected.
When the Lbd.t
Lbd.tLbd.t
Lbd.t parameter is programmed with 0 (zero), the LDB
function is disabled.
The LBD is useful in detecting system failures, such us defective
sensors or actuators, loads and power supply, among others.
SA E OUTPUT VALUE WITH SENSOR AILURE
This function defines an output value (user defined) to be assigned to
the control output in the event of a sensor failure.
When the input sensor is identified as broken, the controller switches
the control mode to MANUAL while forcing MV to assume the user
configured value in the 1E.ov
1E.ov1E.ov
1E.ov parameter. This function requires that
one of the alarms be configured as 1Err
1Err1Err
1Err and the 1E.ov
1E.ov1E.ov
1E.ov parameter
(control output percentage) programmed with a value other then 0
(zero).
Once this function is triggered, the controller remains in SAFE mode
(MANUAL control output) even after the sensor failure appears to be
fixed. The operator intervention is required for switching back to
AUTO mode.
1E.ov
1E.ov1E.ov
1E.ov values are only 0 and 100 % when in ON/OFF control mode.
For P D control mode any value in the range from 0 to 100 % is
accepted.
USB INTER ACE
The USB interface is used for CONF GUR NG or MON TOR NG the
controller. The NConfig software must be used for the configuration.
t makes it possible to create, view, save and open configurations
from the equipment or files in your computer. The tool for saving and
opening configurations in files makes it possible to transfer
configurations between pieces of equipment and to make backup
copies. For specific models, the NConfig software also makes it
possible to update the firmware (internal software) of the controller
through the USB.
For MON TOR NG purposes you can use any supervisory software
(SCADA) or laboratory software that supports the MODBUS RTU
communication on a serial communications port. When connected to
the USB of a computer, the controller is recognized as a conventional
serial port (COM x). Use the NConfig software or consult the
DEV CE MANAGER in the Windows CONTROL PANEL to identify
the COM port that was assigned to the controller. Consult the
mapping of the MODBUS memory in the controller’s communications
manual and the documentation of your supervisory software to
conduct the MON TOR NG process.
Follow the procedure below to use the USB communication of the
equipment:
1. Download the NConfig software from our website and install it
on your computer. The USB drivers necessary for operating the
communication will be installed together with the software.
2. Connect the USB cable between the equipment and the
computer. The controller does not have to be connected to a power
supply. The USB will provide enough power to operate the
communication (other equipment functions cannot operate).
3. Open the NConfig software, configure the communication and
start recognition of the device.
The USB interface S NOT SEPARATE from the signal
input (PV) or the controller’s digital inputs and outputs.
t is intended for temporary use during
CONF GURAT ON and MON TOR NG periods. For the
safety of people and equipment, it must only be used
when the piece of equipment is completely
disconnected from the input/output signals. Using the
USB in any other type of connection is possible but
requires a careful analysis by the person responsible
for installing it.

N1040T Controller
NOVUS AUTOMATION 3/7
TIMERS
This controller contains two timers that can operate independently of
the control output.
T1 TIMER
The T1 timer is the main timer. ts time interval is defined in minutes:
seconds (MM:SS) and allows various operating modes:
There are four starting modes for T1:
RUN T1 starts when the control outputs are enabled (RUN=
YES).
SP T1 starts when the PV value reaches the SP value.
starts upon pressing the key. Once the timer is
initiated, pressing again the key stops and resets the
timer. Pressing the key once more, a new timer cycle
takes place.
DI T1 starts upon command of the Digital nput (dry
contact). The timer is triggered on a high signal from the
D (closed contact) and the timing starts. f the D goes
low (open contact) before the end of the timer, the timer
is interrupted and a new cycle will start when a new high
signal is received on the D .
Releasing the Digital nput while the timer is running
causes T1 to stop and reset. Closing again the Digital
nput initiates a new timer cycle.
Note: f the run parameter has been manually set to NO (control
disabled), the options to trigger via the key and D do not permit the
reactivation of control (RUN= YES). f RUN=NO (control output
disabled), the timer remains disabled regardless of the key and
Digital nput commands.
Operating Modes of Timer T1
The T1 timer has three different modes of operation. The modes of
operation define the behavior of the outputs associated with the
timer. The T1 timer can be associated to any of the outputs OUT1,
OUT2, OUT3 and OUT4, whose behavior can be configured to work
in three distinct modes:
off
offoff
off The output of T1 is turned Off the end of T1. Output
turns on when timer starts and turns off when the time
defined in T1 has elapsed.
The A1 sign remains lit while the timer is running and
flashes after the T1 interval is completed.
On
OnOn
On The output of T1 is turned On at the end of T1. Output
remains off during the timer interval and turns on at its
end, remaining so until the start of a new timer cycle.
The A1 sign flashes during the whole timer duration and
it is turned on continuously after the timer is elapsed,
indicating that the Output is ON.
On.x
On.xOn.x
On.x The output of T1 Stays On at the end of T1. Output is
turned on at the beginning of the timer cycle and
remains in this state even after the timer has elapsed.
The A1 sign is lit during the time counting and flashes
at the end of the temporization, indicating that the
output is ON.
T2 TIMER
T2 is the secondary timer and is activated at the end of T1. The T2
output can be associated to any free controller output. This output
remains ON during the whole T2 duration.
The indicator A2 indicates the condition of timer T2:
T2 is running, A2 is on.
T2 has not started or has already finished, A2 is off.
UP/DOWN TIMER COUNTING
Both timers can be configured to display the counting in incrementing
(UP) or decrementing (DOWN) modes. n UP mode, the counting
starts at zero and counts up until the time setting is reached. n
DOWN mode, the display starts showing the time setting and counts
down to zero.
TEMPERATURE CONTROL OUTPUT DURING TIMER
OPERATION
During the T1 and T2 operation the control output works normally.
However, the behavior of the control output can be configured to stop
after the time T1 + T2 has elapsed, forcing RUN=NO. See the
description of the parameter T.E.(.0.
T.E.(.0.T.E.(.0.

STARTUP
When the controller is powered up, it displays its firmware version for
3 seconds, after which the controller starts normal operation. The
value of PV and SP is then displayed and the outputs are enabled. .
t is in the lower display that the value of SP is displayed. This is the
Indication Screen.
n order for the controller to operate properly in a process, its
parameters need to be configured first, such that it can perform
accordingly to the system requirements. The user must be aware of
the importance of each parameter and for each one determine a valid
condition.
The parameters are grouped in levels according to their functionality
and operation easiness.

ACESS PASSWORD
The protected levels, when accessed, request the user to provide the
Access Password for granting permission to change the
configuration of the parameters on these levels. The access
password is entered in the parameter PASS
PASSPASS
PASS that is show in the first
protected cycle.
The prompt PASS
PASSPASS
PASS precedes the parameters on the protected levels.
f no password is entered, the parameters of the protected levels can
only be visualized.
The Access Password is defined by the user in the parameter
Password Change (PAS.(
PAS.(PAS.(
PAS.(), present in the Calibration Level. The
factory default for the password code is 1111.
PROTECTION ACCESS PASSWORD
The controller provides a system of security that helps to prevent the
entering of many passwords in the hope of finding the correct one.
The protection system built into the controller blocks for 10 minutes
the access to protected parameters after 5 consecutive incorrect
attempts at guessing the correct password.
MASTER PASSWORD
The Master Password is intended for allowing the user to define a
new password in the event of it being forgotten. The Master
Password doesn’t grant access to all parameters, only to the
Password Change parameter (PAS(
PAS(PAS(
PAS(). After defining the new
password, the protected parameters may be accessed (and
modified) using this new password.
The master password is made up by the last three digits of the serial
number of the controller added to the number 9000. As an example,
for the equipment with serial number 07154321, the master
password is 9 3 2 1.
Controller serial number is displayed by pressing for 5 seconds.
DETERMINATION O PID PARAMETERS
During the process of determining automatically the P D parameters,
the system is controlled in ON/O in the programmed Setpoint. The
auto-tuning process may take several minutes to be completed,
depending on the system. The steps for executing the P D auto-
tuning are:
•Adjust the desired SP of the process. Select the process
Setpoint.
•Enable auto-tuning at the parameter “Atvn
AtvnAtvn
Atvn”, selecting FAST
FASTFAST
FAST
or FULL
FULLFULL
FULL.
The option F
FF
FAST
ASTAST
AST performs the tuning in the minimum possible time,
while the option FULL
FULLFULL
FULL gives priority to accuracy over the speed.
During automatic tuning the indicator TUNE remains lit on the
faceplate of the controller. The sign TUNE remains lit during the
whole tuning phase. The user must wait for the tuning to be
completed before using the controller.
During the execution of automatic tuning, PV oscillations can be
introduced into the process around the setpoint.
During auto tuning period the controller will impose oscillations to the
process. PV will oscillate around the programmed set point and
controller output will switch on and off many times.
f the tuning does not result in a satisfactory control, refer to Table 05
for guidelines on how to correct the behavior of the process.
